Small bubbles bad for fish?

[Aquarium guy person]

I got a new sponge filter and It is making a lot of very tiny bubbles(smaller than salt grains). The tank is just absolutely filled with them and I don’t know if this is bad

 

[PheonixKingZ]

Is it just on the surface? Or is it literally filling the whole tank. Would it be possible to post a picture of your tank? Your air output might be to high.

 

[Aquarium guy person]

they are filling the whole tank I will post a picture after this post

There were more but I decreased the flow for now

 

[PheonixKingZ]

Oh, defiantly no problem. Just the keep the flow decreased and you shouldn't have a problem. Might I suggest cleaning those plastic plants? Just take them out and scrub them with hot water. Don't use any soap or chemicals.

I’ve done that but I just don’t like to really disturb the way it already looks.i will be having java moss in there soon from my lfs

Good, lives plants are better than fake IMO.

All I have in that tank is gravel, no sand or other stuff in the bottom. I don’t know if plants can live in that, also I don’t want to be adding fertilizer

 

[Aquarium guy person]

Can those bubbles be harmful though because I want to increase the flow

There are plenty of plants that absorb what they need from the water. Floating plants like hornwort, anacharis and water sprite to name a few and you can also plant them in the gravel. Also many types of ferns like Java fern, African water fern and crested java fern that you can attach to driftwood and stones. Plants that you need to plant in the gravel you can use plant tabs to feed them. You can add a little fertilizer if you want to the water but most plants get what they need from fish waste in the water or the plant tabs.

The bubbles are not harmful. Many live plants can live in gravel. As @Retired Viking said. Also try Anacharis. It’s a very pretty, hardy plant.

If/when we do sufficient routine partial water changes to maintain and ensure high water quality, plants will need some modest fertilizer along with sufficient light intensity/duration in order to do well. Like your fish, plants need food.
Now some tanks may not have sufficient lighting to support some rooted plants, but nearly all tanks will support fast growing floating plants that are near the light. Also many slow growing plants with rhizomes like java fern and anubias will do well in lower light...while most "carpet" plants will fail.
It is a hobby myth that plants do well in 'dirty' water as like fish, plants do best in clean water.
The beauty of live plants is that they convert nutrients (aka pollution) into plant tissue that we eventually remove by trimming. However, fish food and fish/plant waste can't really support them well. I know, adding fertilizer seems counter productive, but a little fertilizer goes a long way to supporting plants that use ammonia (and other 'stuff') as their food source.

As to the tiny bubbles, I'll confess that I'm confused. I have several sponge filters and none of them produce tiny bubbles? Having 'said' that, air bubbles are not harmful to fish. I once had a bubble wall on one side of a tank and some fish seemed to love to 'ride' up and down in the bubble stream. Like a ride at Disney Land.
------
As to plants in gravel, you may need 1-2" to support rooted plants, but as previously mentioned, plants can live fine in gravel...in some cases, much better than in some very fine sands. Still, a tank can look quite nice with java moss, java fern, anubias (attached to wood or rock), and floating plants...with only a very thin layer of gravel (no rooted plants).

It’s a dual sponge filter and the output for the water is above the water line I will post a picture.

@Deanasue, I here you have sponge filters in with your cherry shrimp. Do you ever have the problem of “to many bubbles”?

@Aquarium guy person, why are you concerned that there are to many bubbles?

 

[Aquarium guy person]

I really don’t know I’ve just never had that happen before
